Reprinted from yesterday's late editions.

Watergate Judge John Sirica has handed down yet another opinion on what some called "the case of the century." Commenting Thursday night on Nixon aide H. R. (Bob) Haldeman's book. "The Ends of Power," Sirica observed that he had read the excerpts but that "I think they ought to buy my book."

Steve Martindale said the postman brought him a publisher's once-in-a-lifetime offer to buy Richard Nixon's book, "Memoirs."

Numbered and autographed, only 2,500 copies are to be available at $250 each. Without an autograph, the price for a special leather edition will be dropped to $75. Martindale said he isn't buying any.

He and Sirica were having their say while attending the farewell reception which Italian Ambassador Roberto Gaja and Mrs. Gaja gave at the embassy. Firenze House, Gaja is retiring from the Italian foreign service and will be succeeded later this month by Paolo Pansa Cedronio.

Now deputy secretary general of NATO, Cedronio is a bachelor whom some are sizing up as the social heir apparent to newly married Alejandro Orfila, secretary general of the Organization of American States, who also made Thursday night's scene.

Cedronio will arrive in Washington in time for the American Ballet Theater's March 23 gala starring Mikhail Baryshnikov in "Don Quixote."

Predicted Pierre-Frantz Chapou, Washington man-about-the-arts who will be Cedronio's ballet host, the ambassador "will be assaulted by the ladies." Thanks to Chapou, the ambassador's date that night will be French actress Odile Versois, also known as the Duchess Pozzo de Borgo, and a good friend of Baryshnikov.

Thursday night's party attracted a number of ambassadors and a sizable representation from Washington's official society.
